Something Strange is a supplement for FFG's Genesys RPG, released under their Genesis Foundry licence. The author has categorized it as a Modern Horror Setting, but the supplement will work equally well for Urban Fantasy.
The supplement only spends a few pages detailing the "Setting", but that's because it doesn't need to. Set in the modern world, but with a supernatural twist, there isn't the need for a lot of exposition detailing the world. In fact, that very lack of detail gives the GM and Players using Something Strange the freedom to tailor the setting to their tastes. Without naming specifics, this could be used to emulate any number of book series, movies, or television series with very little effort.
There are a number of new Archetypes and Careers that are suited to the genre, but that could be used in any Genesys game, along with a large selection of new Talents.
Additionally, a few new rules help emphasize the theme, but they are simple and therefore should be easy to implement.
Something Strange has a small but useful section devoted to equipment and vehicles that should cover most situations.
The Adversary section covers some expected monsters (Vampires, Werewolves), but also some unusual choices (Chupacabra, Moth Man), and even named NPCs with a brief backstory ready to drop into a campaign. One of the strengths of Genesys is the ability to easily re-skin Adversaries, meaning a GM can use these in any game (or use Adversaries from any other Genesys product for a Something Strange campaign).
I purposely left one aspect of the supplement to the end of my review: Vampires and Werewolves. The author devised a brilliant way to handle these "monsters" as player characters. He uses Talents to represent them and their abilities, allowing a PC to become either a Vampire or a Werewolf (both not both) after character creation (although they could also spend some of their initial XP to start as one), and then grow in power over the course of a campaign.
It also means that an all Vampire or an all Werewolf campaign could be run using Something Strange, and the characters can all be unique (not to mention adding a twist to the default "Modern Horror" premise).
All in all, this is a welcome addition to the Genesys system!
